Does it also drive you nuts when someone says "try and" instead of "try to," or does your superiority only trigger only when the most basic knowledge is in question? Also, correcting grammar is such bullshit in general. "Try and" is just as grammatical as "try to" because it's just as easily understood, but if you look at English in a prescriptive way, you can get caught up on really inane and specific grammar points. It's just annoying when people pat themselves on the back for knowing the difference between your and you're or there/their/they're when 1) the meaning is never really obfuscated when the wrong form is used, and 2) the rules are so basic that knowing them puts you absolutely no higher than someone who doesn't—knowledge of prescriptive grammar rules doesn't translate to intelligence. I just despise this attitude. It's grammar for people who don't actually care to learn about grammar.
